+ 1. a.mask and getmask(a) will now return ma.nomask constant, which is defined as an array boolean scalar False_.
+      If your code relies on an explicit "m is None" check, it should be changed to "m is nomask."  In many case this check
+      will now be redundant because nomask provides full array interface. For example "m is None or not sometrue(m)"
+      can now be written as "not m.any()".
